My face got very swollen yesterday. It started as if I was bitten on the cheek. Then my right side started to become swollen an it felt itchy. My left eye then begun to swell. I took benadryl . After a few hours my right arm felt like it had gone to sleep. This lasted about 2 hours then it went away. The selling went down but the next day there was still some swelling above my left eye and around the right side of my mouth.
